Light. Portable. Excellent handling. Sharp. And amazingly fast autofocus. The 400mm f/5.6L is all of these things, and a premier choice for wildlife and nature photographers--one of the finest telephoto lenses in the world for fast-moving subjects such as birds in flight or motor sports. It uses UD-glass elements to provide outstanding optical quality, even wide-open, and image quality is preserved when used with either the EF 1.4x II or EF 2x II tele extenders. It accepts 77mm filters, and has a built-in removable tripod collar.

I have been using Canon lenses since a long time, and I never had any problem while using them.

When I was reviewing its features, I found that it was ideal for my requirements. Apart from being lightweight, this lens allows me to focus quickly and provides adequate sharpness. I am quite happy that I bought this amazing Canon lens.

This is the magnifying factor of a lens. Macro lenses will often be described by their “magnification factor”. A lens with a 1:1 magnification factor produces a projected image on the sensor which is the same as the subject.

The individual pieces of glass that form the overall optical construction. Most lenses have between four and eleven elements to bend the light rays to ensure a perfectly formed image appears on the light sensitive surface, such as a film or CCD. The elements are arranged in groups and may be seen in specification sheets as, for example, 6 elements in 4 groups. That configuration may have two single elements and the other four grouped in pairs.
